TIRE AND FELLY DRILL.

SPECIFICATION forming part of Letters Patent No. 678,555, dated July 16, 1901. Application filed February 28, 1901. S ri 4 3 (N0 l- To all whom, it may concern:

Be it known that I, FRIEDRICH WILHELM FGRSTER, a resident of Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improve ments in Tire and Felly Drills; and I do here by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved tire and felly drill, the object of theinvention being to provide a device of this character which can be quickly secured in position on a wheel to bore a hole or holes through the tire and felly thereof.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective View illustrating my improvements. Fig. 2 is a plan view, and Fig. 8 is a View of a modified form oflever K.

A represents a section of wheel, of ordinary construction, having the wooden felly and metal tire B and on which my improved drill is shown in the drawings in an operative position.

F represents a sleeve having secured at each end lugs G and T, respectively, parallel to each other and depending from the sleeve. The inner lug T is held against the inner face of the felly A by a screw E, which latter is screwed through a bar D, adjustably connected at one end to the lug G by a bolt V, disposed in a slot in the lug G and secured in place by a nut. The other end of the bar D is bent at right angles and made in the form of a hook G to engage the inner face of felly A, so that when the screw E is forced against the tire B it will draw the hook C and lug T tight against the Wheel-felly and secure the sleeve F rigidly in position.

A rod H is mounted in the sleeve F and is secured at any adjustment therein by a thumb-screw Z, and said rod H is bent at right angles at its outer end and has secured therein a bearingsleeve Q, in which a shaft R is revolubly mounted. The shaft R carries at its inner end a removable boring bit An angular collar N is mounted on the shaftR between the ring 0 and crankl? and carries a pin WV, on which one end of a link M is pivotally secured, the other end of said link M being bifurcated and the bifurcated members made with alined holes to'receive a pin X. The pin X is adapted to be passed through any of the series of holes in link M and through any one of a series of holes L in one end. of a lever K, located between the bifurcated members of the link M. The lever K is fulorumed between its ends on a pin Y on a sleeve or collar J, adjustably secured on the inner end of rod H and is provided at its free end with a suitable handle or handhold, as shown.

Instead of providing the lever K with a series of holes I might make the same with an elongated slot and with a series of notches for the reception of the pin Y to permit of quick adjustment of the lever.

The drill S may have a shoulder, as shown, to ream out the hole made, and thus fit the hole for the immediate reception of the tirebolt.

The operation of my improvements is as follows: The wheel A, with the tire B thereon, is placed in a horizontal position on any desired support. The hook O and lug T are insorted on the inner side of the felly and the nut V adjusted in the lug G to center the screw E on the tire B, when it is forced against the tire to tightly bind the hook O and lug T against the felly and hold the sleeve 15 and parts supported thereby in position, and by means of the screw Z the rod H can be adj usted to center the drill S on the tire. The

operator then draws toward him with his left hand the free end of lever K, and thus, through the medium of link M, moves the shaft R inward and the boring-tool S against the tire, and by feeding the tool forward with his left hand and turning crank P with his right he quickly bores through the tire B and felly A.

The bifurcated end of link M can be adjusted on the lever K by moving the pin X from one hole to another therein and by moving the lever K (when it is in theform shown in Fig. 3) so as to move the pin from notch'to notch therein.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without depart ing from the spirit and scope of my inventioh, and hence I would have it understood that I do not limit myself to the precise details set forth, but consider myself at liberty to makesuch slight changes and alterationsas fairly fall within the spirit and scope of my invention.

Having fully described my invention, What l claim as new, and desire to secure by Letters Patent, is-

1.v Ina tire andlfelly drill, the combination with a boring-tool holder, of a clam pin g-frame carrying said holder and constructed to be secured to and carried by said tire and felly, means carried. by the frame for moving the tool-holder longitudinally and means also carried' by said frame for revolving the toolholder.

2. In a tire and felly drill, the combination with aboring-tool holder, of aframe carrying said'tool-holder and providedwith means'for clamping the frame to the tire and felly and centering the-boring-tool, and means carried by said frame for-operating the tool-holder.

3. In a tire and felly drill, the combination witha boring-tool, of means for centering the same on a wheel-tire, a lever for-moving the tool longitudinally and a crank for turning it.

4. In a tire and felly drill, the combination with asleeve and means for rigidly holding the same on a wheel, of a rod adjustably se cured in said sleeve, a boring tool revolubly supported by theouter end-of the rod, a lever 1 fulcrumed between its ends at the inner end of said rod, and a link connectingone end of said lever and the boring-tool to move'the latter forward and backward when the free end of the lever is moved.

5. In a tire and felly drill, the combination with a rod and means for rigidly securing the same on a Wheel, of a bearing carried by the bent outer end of the rod, a shaft in said hearing, a boring-tool carried by the inner end of :said shaft, av crank secured to the outer end of the shaft, a lever fulcrumed between its ends to the inner end of the rod, and a link adjustably connected at one end to one end of the lever and at its other end to the outer end of'theshaft.

6. In a tire and felly drill, the combination with a rod and means for rigidly securing thesame to and supporting it on the tireand felly of a wheel, of a bearing carried by the bent outer end of the rod, a shaft revolubly and longitudinally movable in said bearing, collarson said shaft-to'limit-its movement,- aboring-t'ool on the-inner endof the shaft, a crank on its outer end and means for moving said shaft longitudinally in its bearing;

7. In a't'ireand felly'drilhthe combination with a sleeve and means-for boring a hole'supportedthereby, of depending lugs at'eachend' of said sleeve one of which to be disposedagainst the inner face of a wheel-felly, the other made with an elongated slot, a bar, a bolt adjustably securing one end-ofthe same in said'slot, the other end of said bar bent'to form a hook to engagethe inner face of awheel-felly, anda set' screw in saidbarto engage the wheel-tire and clampthe wheelbetween the inner lug on the sleeve, and the hook on the bar, on one side and thescrew on the other.

In testimony whereof I have signed this specification in the presence of two-subscrib ing witnesses.
